What Our NSF/ANSI Certifications Actually Mean for Your Family

NSF/ANSI International is the gold standard for water filtration certification — independent, rigorous, and trusted by regulators worldwide.

  • NSF/ANSI 42

    Chlorine, Taste & Odor

    Certifies that the filter reduces chlorine, taste, odor, and other aesthetic contaminants that affect how your drinking water looks, smells, and tastes. Every sip, fresher.

  • NSF/ANSI 53

    Health-Based Contaminant Reduction

    The most critical certification — certifies reduction of health-threatening contaminants including lead, volatile organic compounds (VOCs), chromium, and cysts like Cryptosporidium and Giardia.

  • NSF/ANSI 372

    Lead-Free Materials

    Certifies that every part of the filter touching your water is lead-free by law — weighted lead content at or below 0.25%. Safety built into the hardware itself, not just the filtration media.

  • NSF/ANSI 401

    Emerging Contaminant Reduction

    Certifies reduction of trace pharmaceuticals, herbicides, pesticides, BPA, and flame retardants — 15 modern contaminants that older certification standards didn't even test for. Critical for modern water safety.

  • NSF/ANSI P473

    PFOA & PFOS Reduction

    Certifies reduction of PFOA and PFOS — two of the most persistent "forever chemicals" in the PFAS family, linked to serious health concerns and found in water supplies nationwide.

  • CSA B483.1

    Canada Certification

    Canada's national standard for drinking water treatment systems — independently verified for contaminant reduction, material safety, and structural integrity.

  • I ran hot water through my filter is it still good
    The F2 & F5 Systems should not be used to filter Hot Water, however a small amount by accident will not harm the filter
  • My F2/F5 System drips some water from the filtered side when not filtering water
    It is normal for a small amount of water to drip from the filtered side when not in use. The amount of water depends on how well the filtered pathways holds a vacuum. The drips are water draining out of the filtered side. The Angle the unit is installed at can increase and decrease this flow.
  • Is the Aerator removable
    Yes, the aerator unscrews and allows for dishwasher or another sprayer hook up. This may also be done to “Clean” any debris form the Aerator Screen.
